[R] strange behavior when reading csv

[Thomas Keller]

Martin,
"The number of data columns is determined by looking at the first five  
lines of input (or the whole file if it has less than five lines), or  
from the length of col.names if it is specified and is longer. This  
could conceivably be wrong if fill or blank.lines.skip are true, so  
specify col.names if necessary."
This may not be work for you, but if you can figure out the longest  
row for each file, you could create a col.names object that would  
force read.csv() to read all the columns.
e.g.
 > probNames <- paste("V",1:43)
 > probData <- read.csv("/Users/kellert/Documents/Computing/R_work/ 
problem.txt", sep = ";", header = FALSE, fill = TRUE, col.names =  
probNames)

cheers,
